The invention discloses a kind of fire-resistant waterproof compound insulating material and preparation method thereof, wherein fire-resistant waterproof compound insulating material is with expanded and vitrified small ball as dispersion phase, with polyisocyanates, the product that polyhydric alcohol conjugate material and waterglass mixing generate is continuous phase, wherein polyhydric alcohol conjugate material is by polyhydric alcohol, foaming agent, catalyst, cross-linking agent, foam stabilizer forms, described polyhydric alcohol is polyether polyol and/or PEPA, the quality of described polyhydric alcohol and waterglass and be 100:120～130 with the mass ratio of polyisocyanates, described polyhydric alcohol is 10:10～100 with the mass ratio of waterglass.The fire-resistant waterproof compound insulating material of the present invention has the advantages that intensity, fire resistance and heat insulating ability combination property are high.
Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of fire-resistant waterproof complex heat-preservation
Material and preparation method thereof.
Background technology
At present, in the measures implementing building energy conservation, wall thermal insulating is considered as most to go it
Effectively.Therefore heat insulating material and combined wall are all being greatly developed in countries in the world.And one
Kind of excellent insulation material not only should have the heat that the performance of good resisting heat flow transmission is the biggest
Resistance, little heat transfer coefficient, but also should have good fire prevention, waterproof, weather-proof, durable
And sustainable developability.
Hard-foam polyurethane material is as the insulation material of a kind of excellence, and its heat conductivity is low, is only
0.018～0.023W/ (m.K), is minimum in the most conventional insulation material；In addition it also has
The advantages such as light weight, adhesion strength are strong, waterproof, sound insulation, aging resistance.Therefore, at building energy conservation
Will there be the biggest development space in field.But use as building thermal insulation material, need to improve further
Its fire line, compressibility and heat stability (such as underground heat pond heat insulating work), this is accomplished by
Ensureing on the basis of its thermal and insulating performance, minimizing cost, improve fire prevention, heat-resisting,
Durable and mechanical property, in order to obtain more excellent combination property.By polyurethane and some nothing
Machine heat-insulating granules such as expanded and vitrified small ball Particles dispersed, utilizes glass bead granule relative moderate
Price, excellent fire protecting performance, good durable and weatherability, polyurethane is changed
Property can yet be regarded as a kind of effective method.
In inorganic heat insulation material, the expansion class granule of broad sense includes that perforate perlite, closed pore are precious
Zhu Yan and glass bead, owing to their own has loose structure, be therefore a kind of good
Insulation material, wherein the heat conductivity of glass bead is minimum up to 0.038W/ (m.K).But in reality
In the application of border, they are typically by the cementation of inorganic coagulation material, make and have necessarily
The hard block goods of shape or thermal insulation mortar use, due to the high-termal conductivity of inorganic coagulation material,
The heat-insulating property making this based article final drastically declines；Additionally, the water absorption that goods are high, also
It is the problem that must solve of this type of material, it is contemplated that inorganic gel materials is used organic hard polyurethane foam
Body replaces, and utilizes the caking property of polyurethane excellence and water proofing property to prepare lightweight, heat conduction waterproof, low
The novel glass bead product of coefficient, thus overcome self heat conductivity of expanded and vitrified small ball goods
High shortcoming, will for playing inorganic heat insulation material environmental friendliness, raw material and being easy to get, stable performance etc.
Advantage creates conditions, and this also will play important work for glass bead under new energy-conservation form again
By the new opportunity of offer.
In view of above-mentioned existing building heat preserving material has many defects, the present inventor actively adds
With research and innovation, with a kind of fire-resistant waterproof compound insulating material of invention and preparation method thereof, disappear
The defect existed except prior art so that it is more there is practicality.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the invention provides a kind of intensity,
Fire resistance and the high fire-resistant waterproof compound insulating material of heat insulating ability combination property.
In order to solve above-mentioned technical problem, present invention employs following technical scheme:
Fire-resistant waterproof compound insulating material, it is with expanded and vitrified small ball as dispersion phase, with many isocyanides
The product that acid esters, polyhydric alcohol conjugate material and waterglass mixing generate is continuous phase, wherein polyhydric alcohol
Premixed systems is made up of polyhydric alcohol, foaming agent, catalyst, cross-linking agent, foam stabilizer, described polynary
Alcohol is polyether polyol and/or PEPA, the quality of described polyhydric alcohol and waterglass and
It is 100:120～130 with the mass ratio of polyisocyanates, described polyhydric alcohol and the quality of waterglass
Ratio is 10:10～100.
As preferably, the matter of described polyhydric alcohol, foaming agent, catalyst, cross-linking agent and foam stabilizer
Amount ratio is 100:(5～20): (0.1-0.5): (0-0.5): (1～10).
As preferably, described expanded and vitrified small ball is the expanded and vitrified small ball granule of different-grain diameter,
Density is 80～200kg/m3。
As preferably, the hydroxyl value of described polyether polyol is 400～560mg KOH/g, average official
Energy degree is 3.5～4.5.
As preferably, described polyisocyanates is toluene di-isocyanate(TDI) (TDI) or diphenyl-methane
Diisocyanate (MDI).
As preferably, described waterglass is sodio waterglass or potassio waterglass, and solid content is
5-50%(weight/mass percentage composition).
As preferably, described expanded and vitrified small ball waterglass, polyisocyanates and polyhydric alcohol group
Pour in mould after closing material cladding mix homogeneously successively, free foaming, room temperature ripening 24h, the demoulding
?.
Another object of the present invention is for providing the preparation of a kind of above-mentioned fire-resistant waterproof compound insulating material
Method, the method and obtain the fire-resistant waterproof that intensity, fire resistance and heat insulating ability combination property are high
Compound insulating material.The technical scheme realizing this purpose is as follows:
The preparation method of above-mentioned fire-resistant waterproof compound insulating material, comprises the steps:
